Abstract
Carboxy phosphorus acid compounds react by a metathesis reaction in a liquid media with tetravalent metal ions to yield layered crystalline inorganic polymers having the empirical formula M(O.sub.3 PR.sub.n COOH).sub.2 where M is a tetravalent metal and R is an organic group covalently bonded to phosphorous and the terminal carboxy group and n is 0 or 1.
